Re: volume button doesn't work after system restore.

Hi,

 

1.      Open Device Manager by clicking the Start button, clicking Control Panel, clicking System and Security, and then, under System, clicking Device Manager. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.‌

2.      In the list of hardware categories, find the device that you want to update, and then double-click the device name.

3.      Click the Driver tab, click Update Driver, and then follow the instructions. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

 Try running System File Checker and see if it helps, here are the steps:


1.     Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.
2.     Click Continue or supply Administrator credentials if prompted.
3.     In the Command Prompt window type the following, and press Enter:
sfc /scannow

 

Here is an article that will give you information on SFC Scan:

If this does not help, then try performing clean boot to check if any third party services are causing this issue, here is the link:
